| Popis: | Randomness of fingerprint texture patterns in the N* phase and its application to security devices providing unique information for confirming authenticity were reported. This proposed device made use of uncontrolled random patterns of fingerprint texture in liquid crystal, although the normal liquid crystal devices mostly use controlled molecular alignment. |
